A/N- Taylor Swift's songs are so perfect for fanfiction! This one is called "Tell Me Why". I was listening to it the other day and thought it would be a perfect song for Lily and Severus. So, here you go. Please review. Constructive criticism is welcome. Flames will be ignored.

As always, I have only borrowed J.K.R.'s characters to corrupt *ahem* play with. I promise I will put them back where I found them when I have finished…

"Tell Me Why"

I took a chance, I took a shot

And you might think I'm bulletproof, but I'm not

You took a swing, I took it hard

And down here from the ground I see who you are

When Lily Evans first saw the greasy-haired boy on the playground that day she could not have forseen the events that would follow that faithful day.

"Mudblood!" The words still rang in her mind.

I'm sick and tired of your attitude

I'm feeling like I don't know you

You tell me that you love me then you cut me down

And I need you like a heartbeat

But you know you got a mean streak

Makes me run for cover when you're around

And here's to you and your temper

Yes, I remember what you said last night

And I know that you see what you're doing to me

Tell me why

She was his best friend, but lately he had been hanging out with some pretty messed-up Slytherins. She had a crush on him, but this new Sev was comepletely different from the one she really loved.

You could write a book on how to ruin someone's perfect day

Well I get so confused and frustrated

Forget what I'm trying to say, oh

She couldn't understand why he wanted to be a Death Eater. Surely his own parents had showed him how horrendous greed and evil were. His father had been a freaking alcoholic!

I'm sick and tired of your reasons

I got no one to believe in

You tell me that you want me, then push me around

And I need you like a heartbeat

But you know you got a mean streak

Makes me run for cover when you're around

Here's to you and your temper

Yes, I remember what you said last night

And I know that you see what you're doing to me

Tell me why

She wanted the old Severus Snape back. She wanted to tell him she loved him. She wanted to her friends that sometimes Slytherins were nice.

Why do you have to make me feel small

So you can feel whole inside

Why do you have to put down my dreams

So you're the only thing on my mind

She could forgive all of his other mistakes, forget all his other faults, but she could not forgive him calling her that unforgivable word. "Mudblood!"

I'm sick and tired of your attitude

I'm feeling like I don't know you

You tell me that you want me then cut me down

I'm sick and tired of your reasons

I've got no one to believe in

You ask me for my love then you push me around

Here's to you and your temper

Yes, I remember what you said last night

And I know that you see what you're doing to me

Tell me why

Why, tell me why

He had to know he was hurting her. She resolved to leave her feelings in the dust, and confront him. She would put things straight. After all, she should have done this moths ago.

I take a step back, let you go

I told you I'm not bulletproof

Now you know

"It's over. You've chosen your way, and I've chosen mine."
